A false step brought her suddenly to the ground. 一次失足突然让她跌到地上。
Be sure where your next step will fall so that you will not stumble. 保持居安思危的思想以便你不会失足。
If she does not mind the step,she'll fall down. 如果她不注意台阶，她就会摔倒。
When we step to the new world, we are like a child toddling, fall over for the first step.But it doesn't mean to failure as we made the first step after all. 我们迈入新世界时，像一个蹒跚学步的幼儿，刚走第一步就摔倒了，但这不是失败，毕竟我们已经迈出了这一步。
